2.3.2
Standby (Sleep) mode
Standby (sleep) mode is the lowest power mode of STM 550x and is the out of the box state
of STM 550x upon delivery. It is intended to be used during extended periods without oper-
ation such as device storage or transport.
In standby mode, STM 550x stops operation and conserves as much energy as possible. All
functionality
–
except those needed to return to standard operation mode
–
are disabled in
this mode.
Standby mode can be selected using the LRN button as described in chapter 2.2.1 or using
the MODE field of the FUNCTIONAL_MODE NFC register as described in chapter 8.5.11.
2.3.3
Learn mode
In learn mode, STM 550x will transmit a Teach-in telegram to communicate the device source
address and security key to a receiver. After that transmission, STM 550x will return back to
standard operation mode.
Learn mode can be selected using the LRN button as described in chapter 2.2.1 or using the
MODE field of the FUNCTIONAL_MODE NFC register as described in chapter 8.5.11.
2.3.4
Function test mode
In Function Test Mode, STM 550x will measure and report the status of the integrated sensors
at the highest possible rate to verify the sensor functionality.
STM 550x can be set into function test mode via the LRN button as described in chapter 2.2.1
or via the MODE field of the FUNCTIONAL_MODE NFC register as described in chapter 8.5.11.
Function Test Mode will be active for 120 seconds unless the LRN button is pressed before or
